Multiphase Computational Fluid Dynamics of Rotary Shaft Seals

The primary task of rotary shaft seals is to prevent an unwanted fluid transfer between two areas. In passages gearboxes, for example, avoid the leakage transmission oil ambient air. This means flow in lubricant film sealing gap edge and surface consists at least phases. Taking phenomenon cavitation into account, three study aims provide in-depth understanding multiphase seals. As experimental studies processes on a microscale have proven be quite difficult, simulation-based approach applied. Computational dynamics (CFD) serves compute transient flows gap. computational domain three-dimensional model film. results show hydrodynamic pressure buildup dynamic phase interactions during operation. provides far-reaching insights evidence lubrication mechanism
